It can follow directly behind you, from a fixed point, or travel along a fixed flight path.

It's waterproof, small enough to fit in a backpack, and weighs just under three pounds.

The tracker, which fits on your wrist, contains an accelerometer and an audio recorder.

That way, Lily can tell when your trajectory changes — like when you go off a jump while skiing or snowboarding — and knows to take quick snapshots while you're in the air. It records all the audio from your wrist and adds it to the video automatically, pairing the bird's-eye view with what you hear on the ground.

Lily is releasing the drone in February 2016 at the latest, and it will cost $999. If you preorder it, however, it's just $499.
